Saft Seanergy Energy Storage Systems Approved by NMA

Saft has obtained approval of its Seanergy marine energy storage system by the Norwegian Maritime Authority (NMA) for use in a variety of hybrid and fully electric propulsion applications.

Saft is the only manufacturer of marine lithium-ion (Li-ion) batteries to use the Li-ion Super-Phosphate (SLFP) chemistry which offers the highest levels of safety, performance and reliability.

The approval process was based on simulated thermal runaway tests carried out on the Seanergy systems by an independent laboratory in August 2016. During the propagation test 1, a cell was forced into a thermal runaway situation by a specific device inserted inside the cell. The test was performed three times. Thanks to the Super-phosphate chemistry, the batteries passed the test on each occasion with no uncontrolled event, no fire and no explosion, with nearby cells remaining in a safe condition and no propagation to neighboring modules and without any active means of fire suppression.

“The NMA approval is a major step for Saft Marine systems, it is a key recognition of our Li-ion Super-Phosphate (SLFP) chemistry, which offers a very high level of safety” said Didier Jouffroy, marine product manager. “Saft’s marine battery technology has been adopted by some of the world’s most innovative and prestigious vessels for applications where environmental performance, safety and cost efficiency are essential.”
